Low overall PM 2.5, light PM in California

PM 2.5 levels were very low today, with only Code Yellow (Moderate) levels of PM 2.5 beng seen in the Pacific Southwest and the Pacific Northwest, along with the Northern Plains States and the Great Lakes region (AirNow, top left). There was also some Code Orange (Unsafe for Sensitive Groups) seen in California. This PM 2.5 in California is due to small wildfires in this area. The smoke coverage can be seen in NOAA's HMS map, top right. The smoke in this area could not really be seen due to heavy smoke coverage in the region (NASA's MODIS Terra, bottom left).
